Google Identity Toolkit、Google OAuth、Firebase Auth 和 Google+ 登录有什么区别 [英] What is the difference between Google Identity Toolkit, Google OAuth, Firebase Auth and Google+ sign in

问题描述

据我所知，Google Identity Toolkit 提供了一个用于使用不同帐户(如 Facebook、Yahoo 等)登录的层，但这与 Google OAuth 实现有何不同?而关于Google+的登录，还是使用OAuth，但是只允许谷歌账号登录?

For my understanding, Google Identity Toolkit provides a layer for login with different accounts, like Facebook, Yahoo etc. but how does that differ from the Google OAuth implementation? And regarding Google+ sign in, it is still using OAuth, but only enables login for Google accounts?

推荐答案

截至 2018 年 12 月 28 日的更新:Google 正在推出一项名为 Cloud Identity Platform 的新服务.这基本上是面向所有 GCP 客户的 Firebase 身份验证.

Update as of December 28, 2018: Google is pushing a new service called Cloud Identity Platform. Which is basically Firebase Authentication just for all GCP customers.

与 Firebase 身份验证一样，此服务为任何身份验证平台提供了一个抽象层(从 GA 开始使用简单的 2 因素身份验证)

This service offers, like Firebase Authentication, an abstraction layer to any authentication platform (with easy 2-factor authentication starting at GA)

Google Sign-In 和 Smart Lock 都只是 Firebase 身份验证和 Cloud Identity Platform 客户端 SDK 使用的底层低级"技术.

Google Sign-In and Smart Lock are both only the underlying "low level" technologies used by the Firebase Authentication and Cloud Identity Platform client SDKs.

截至 2016 年 6 月 15 日的更新:原始答案(下方)中提到的指南似乎未及时更新 - Google Identity Toolkit 似乎即将淘汰，显然已被Firebase 身份验证，该指南中甚至没有提到.

Update as of June 15, 2016: It seems the guide mentioned in the original answer (below) is not kept up to date - the Google Identity Toolkit seems to be on its way out, apparently absorbed into the Firebase Authentication, which is not even mentioned in that guide.

检查当前 Google 身份验证解决方案的更好起点可能是登录 + 身份"图标href="https://developers.google.com/products/" rel="noreferrer">产品 页面.

Maybe a better starting point for checking the current Google authentication solutions might be the "Sign In + Identity" icon on the Products page.
